Arm Lang is ARM 9, in order to test use LPC2104 in Keil tools v5.

Option 2: Quicksort You are to convert the following C quicksort program to ARM assembler. There are numerous websites that describe the quicksort algorithm. Your program must follow these conventions: 1. A calling function must use a stack to pass arguments to the called function. When the called function returns, it is the responsibility of the calling function to remove the arguments from the stack. 2. All registers that a called function will be using to perform calculations must first be pushed onto the stack along with the return address in r14. This is typically the first instruction of the function. When it is time for the function to retum, the registers will be restored to their original values. The return address will be popped into the pc. 3. You may use any of the 4 stack types. 4. Make you program scalable so that it is easy to changc the array size 5. Your quicksort sorts an array of unsigned words IDCD nto ascending order, 6. Before sorting you will nced to copy the array to address 0x40000000. Here is a C implementation of a quicksort. void quicksort(unsigned int arr, int left, int right) int min E (left right)/2, inti eft int j right; int pivot arrtmin]: while(left
